Most Common Types of Charges Given by LPD

Most Common Types of Reported Crashes to LPD

Frequency of LPD Traffic Stops by Race

Of an estimated population of Lincoln being, 289,102 there were 43,310 traffic stops by the LPD. A hypothesis test was done on the calculated proportions for the amount of traffic stops done on People of Color, using the Census Estimate as the null hypothesis and results in a Z-score of 25.31.

Frequency of LPD Vehicle Searches by Race

Over 1/4 of the total vehicles searches done by the LPD were on Lincoln’s Black population, which only accounts for approximately 4.4% of Lincoln’s total population. A hypothesis test was also done for this data with the Census Estimate as the null hypothesis again, and the results are quite similar with a Z-score of 24.57.

Age and Race of People Charged by LPD

One of the most notable observations between the graphs of male and female, is the faster decline in the density curves for the female population. This means the the males are making up a large portion of the charges and citations for people in their older ages. In addition, it is quite clear that Lincoln’s White population accounts for the largest amount of older age charges and citations.

Most Common Types of Charges Given by LPD

The four most common types of charges and citations given by the LPD were, Improper Registration, Violate Speed Limit 11-15 Over, Negligent Driving, and No Proof of Financial Responsibility. This is interesting as all four of these have to do with vehicles.

Most Common Types of Reported Crashes to LPD

The four most common types of vehicle accidents reported to the LPD were, Rear End, Right Angle, Parked, and Turning. The right angle types of crashes surprised me as being so high, as it is classified as such if someone is hit in an intersection of two roads without the act of turning.

LPD Traffic Stops per Week

The weekly number of traffic stops if fairly random and doesn’t seem to spike with any particular event except Memorial Day, and in fact around big holidays the number of traffic stops usually decrease or stays about the same. There is a very large spike in the week of 1-14-19 with the highest number of traffic stops in a week being 1361, and the next highest being 1143 in the week of 5-20-19.

Reported Crashes to LPD per Month

It is to be expected that crashes would increase in the winter months because it can often lead to poor driving conditions. This happened to be the case for the spike in crashes for February in Lincoln. February 2019 was one of the highest total snow fall months in Lincoln history, within one of the snowiest winters in Lincoln history. This would help explain the large number of vehicle crashes in both January and February.
